Leanne Lauricella, the founder of special needs goat rescue Goats of Anarchy, said she originally bought the costume for Halloween but quickly realized the calming effect it had on Polly.

Polly has several other costumes, like a unicorn onesie and a peapod onesie, which have been posted on Goats of Anarchy's Twitter. But it's the duck costume that works, thanks to its "hugging" quality, the rescue workers believe.
